Silk Worm Experiment

In 1868, silk worm eggs were imported to Salt Lake City from France. President Brigham Young at once became deeply interest­ed and called the Saints to raise mulberry trees, the leaves of which are used to feed the worms, and a large number of trees were planted in Mount Pleasant. As they grew, many women became involved in the silk producing enterprise and after a time, cocoons were delivered by them in Salt Lake City.
